First of all, I like this story very much because it portray greatly in the aspects of gender inequality of the ancient China. It includes many aspects that can be relate to our lives (eg, how much power can change people...)

Story: 10/10
In some aspects the story drags (as expected from usual historical drama with so many episodes) but overall the storyline is great. VERY GREAT. as said above, those are some reasons I love this drama. Unlike other dramas, it was very very well made and the storyline ain't all about fluffy, cringy, cliche romance. The plot twists are great and in the end what happened to the villians are just so satisfying. Many people disagree when I thought the ending was good and happy. I can't give away too much at this stage. But let's just put it that for me it is a happy ending. The path Yun Xian (Liu Shi Shi) took in the end was right for me, personally.
The romance...it's complicated and many may not like it because it is not typically the kind of romance that is potray in most asian drama. But, for me I think that it was good enough because in the end I didn't really watch the story for the romance but the storyline itself.

Acting/Cast: 10/10
I'm a big big fan of Wallace Huo and Liu Shi Shi. I watched every dram they starred it so I'm happy the have a drama together. That was enough for me to give it a 10. Of course as expected from them they'd do a great job in acting out their characters. Chemistry is on spec and sides character do their roles very outstandingly.

Music: 9/10
I love love love love the OP and END, and OST. Very much. The end.

Rewatch Value: 7.5/10
I gave it quite low despite having enjoying the drama because it is long and once you watch it, that's it. It wraps up and there was no reason for a rewatch.

Overall I RECOMMEND :) for those looking for relaxation, comedy, extremely fluffy romantic happy drama. this might not be for you... but if not then watch it!
